5. www. Clinical trial results.org IMAGINE: Summary Among patients undergoing coronary artery bypass surgery, initiation of the ACE- inhibitor quinapril early post surgery was not associated with a difference in the primary composite endpoint compared with placebo at a median three year follow-up, with data suggesting a possible increased risk during the first three months following surgery. Data from large trials such as EUROPA and HOPE support the use of ACE-inhibitor therapy in stable coronary artery disease patients. Patients in the present study, while post-bypass surgery, were relatively low-risk (mean ejection fraction 60%) and had to be stable post-operatively to be enrolled. Despite these characteristics, early initiation of quinapril within 7 days of surgery was associated with no late benefit.
